Step-by-step explanation:
It’s for sure B the formula for circumference is

Answer:
I am assuming that you are talking about problem 2. so I will answer that.
Step-by-step explanation:
-2x + 6 ≥ 3x - 34
+2x +2x
6 ≥ 5x - 34
+34 + 34
40 ≥ 5x
÷5 ÷5
8 ≥ x
So, x can be anything equal to or less than 8.
Answer:
Graph F
Step-by-step explanation:
Given
x + 3 < 7 ( subtract 3 from both sides )
x < 4
Since x is less than 4 then this is indicated by an open circle at 4 on the number line with the arrow pointing to the left as shown on graph F
We need to build a system of equations:
a + b + c = 127......(1)
b - c = 13..............(2)
a - b - c = 41..........(3)
adding equations (1) and (3):-
2a = 168
a = 84
Substituting for in equation (1)-
84 + b + c = 127
b + c = 43...........(4)
Adding equations (2) and (4):-
2b = 56
b = 28
Finally from equation (2)
c = 28-13 = 15
Answer is Country a had 84 points , b had 28 points and c had 15 points.
